We describe three brachiopod species of the Suborder Productidina from the Ixtaltepec Formation, Carboniferous of the north of Oaxaca State, southern Mexico, found in peri-reef deposits. Stegacanthia bowsheri and Undaria sp. are members of the families Sentosiidae and Monticuliferidae respectively and were found in strata of the Visean (Middle Mississippian). Martinezchaconia luisae , new genus and species of the Family Linoproductidae, was recollected in Bashkirian-Moscovian (Lower-Middle Pennsylvanian) strata. The respective ages are inferred from the index species of brachiopods associated with the productidines herein described.
